To find out how many ml of soft drink and pineapple juice were in the 300ml that Mr. Smith drank, we can begin by determining the overall mixture ratio of soft drinks to pineapple juice.
-
Total Volume of the Mixture:
- Soft drinks: 750 ml
- Pineapple juice: 250 ml
- Total = 750 ml + 250 ml = 1000 ml
-
Proportion of Soft Drinks in the Mixture:
- Proportion of soft drinks = \( \frac{750 \text{ ml}}{1000 \text{ ml}} = 0.75 \)
-
Proportion of Pineapple Juice in the Mixture:
- Proportion of pineapple juice = \( \frac{250 \text{ ml}}{1000 \text{ ml}} = 0.25 \)
Now, Mr. Smith drank a total of 300 ml from this mixture.
Calculating Amount of Each Component in the 300 ml:
(a) How many ml of the 300 ml was soft drink?
- Amount of soft drink in 300 ml = \( 0.75 \times 300 \text{ ml} = 225 \text{ ml} \)
(b) How many ml of the 300 ml was pineapple juice?
- Amount of pineapple juice in 300 ml = \( 0.25 \times 300 \text{ ml} = 75 \text{ ml} \)
Summary:
(a) 225 ml of the 300 ml was soft drink.
(b) 75 ml of the 300 ml was pineapple juice.
